it says
apt-cache performs a variety of operations on APT's package cache. apt-
cache does not manipulate the state of the system but does provide
operations to search and generate interesting output from the package
metadata.
add add adds the names package index files to the package cache.
etc. well, isn't adding things to the package cache changing part of the
system? OK, it should be more clear...
one test is could apt-cache be setuid root?
cat(1) seems to fulfill 'doesn't change system'.

No, the cache is entirely a transparent and non-user visible component of
the APT system. You cannot use apt-cache to change the standard cache in
any way that is user visible.
Anything the add command does to the system cache will be automatically
undone the next time apt-get is run. It's only useful if an alternative
cache is specified on the command line.
